, LATEnALLY-ADJusTAB n DRIVING Box.

Application filed June G, 1925. Serial No. 35,396.-

To all whom it mag concern:

Be it known that I, IVAN O. GARDNER, a citizen of the United States,residing at Somerset, in the county of Somerset and State ofPennsylvania, have invented certain new and useful Improvements inLaterally- Adjustable Driving Boxes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertaiiis tomake and use the same.

My invention relates to laterally adjust able driving boxes. r

The primary object of my invention is to devise a driving box soconstructed and ar-' ranged that the same .may be laterally adjustedwithout removal from under the 10- comotive.

A further object is to devise a box of the working equipment and whichis also char acterized by an ability to compensate for the wear in thepedestal shoe and wedge.

The clearance between the driving wheel hub and box, known as thelateral, must, under present rulings of the Interstate CommerceCommission, be kept within certain definite limits. At this point of thelocomotiv-e, however, due to the frictional contact of the box with thewheel hub, the rate of wearis relatively high and particularly so withlocomotives having comparatively long Many methods have been devisedheretofore for maintaining this lateral clearance, notably the provisionof refacing the driving box with a wear plate of proper design. Thissolution is objectionable in that it is necessary to remove thelocomotive from service for a considerable time. Other methods haveovercome the latter objection by providing a means for adjusting for thelateral play without removing the wheels or boxes from the locomotive,but as they; require extensive changes in standard'equip have naryconstruction, are required, other than" easily removable wearplates, anda slight change only is made-necessary in the present standard box.These and further objects will be set forth in the followingspecification, reference be-' ing had to the accompanying drawings, and

the novel .means by-which said objects are effectuated will" bedefinitely pointed out in j the claims. i

Fig. 1 18 a sectional e'levation,, of my improved driving .box, showingthe same mounted in a frame. I, v Fig. 2 is a section alongthe line 22in Fig. 1, looking in the direction of the arrows.

The numeral 5 represents the frame of a locomotive provided with apedestal composed of the sides 66 which are'united at their bottoms bythe pedestalbrace 7. A

pedestal shoe 8 and a pedestal wedge 9 embracethe sides 66 in the usualmanner and the latter is provided with the customary inclined surfacefor coacting with a similarly inclined, surface formed on one of thesides 6. The driving box 10 is slidably mounted between the shoe 8 and,wedge 9 and proper engagement'of said wedge with said box is obtained bymeans of the wedge bolt llwhich extends through the brace 7,

the upper end of said bolt being operatively connected to saidwedge inany approved manner in order toachieve this result. An

- axle 12 is journaled in the box .10 and a wheel 13 is secured to eachendthereof with the proper lateral clearance from the outer face of eachof said boxes. For purposes of illustration, one box and wheel only areshown in Fig. 2. I 1 The driving box is, generally considered, formed inthe usual manner, but is specifically constructed to be adapted fortrans verse movement relative to the shoe 8 and wedge 9, and thereforeto-the frame 5'. This condition isobtained by forming a plurality ofrecesses 14 in the box 10, one recess being disposed adjacent eachouter-corner of said box. One wall ofeach recess is formed by acontinuation 'of thefae of the box which contacts with the shoe andwedge and the opposite wall thereof forms the shoulder 15, the distancebetween shoulders on the same side of the box being greater, than thedepth of the shoe, the wedge. ;1' t is, ob

side of said members and said box for shifting the latter transverselyto said frame.

The combination with a frame, of wear members mounted therein, adriving box mounted in said members and means, carried by said box,engaging between the sides of said members and said box and transposablefor engagement between the opposite sides of said members and said boxfor shifting the latter transversely to said frame.

11. The combination with a frame, of channel members disposed to embracesaid frame, a driving box mounted in said members and adjusting platesinsertible between said members and box for shifting the lattertransversely to said frame.

12. The combination with a frame, of channel members disposed to embracesaid frame, a driving box mounted in said members and adjusting plates,carried by said box, insertible between said members and box forshifting the latter transversely to said frame.

18. The combination with a frame, of wear members mounted therein, adriving box mounted in said members and adapted for transverse movementrelative thereto, and means engaging between said members and box formaintaining the latter in a plurality of laterally shifted positions.

14. The combination with a frame, of wear members mounted therein, adriving box mounted in said members and adapted for transverse movementrelative thereto, and means, carried by said box, engaging between saidmembers and box for maintaining the latter in a plurality of laterallyshifted positions.

15. The combination with a frame, of wear members mounted therein, adriving box mounted in said members, an axle journaled in said box andprovided with a wheel spaced from said box, and means interposed betweensaid members and box for shifting the latter toward said wheel.

16. The combination with a frame, of

wear members mounted therein, a driving box mounted in said members'andlaterally shiftable relative thereto, an axle journaled in said box andprovided with a wheel spaced from said box, and means engaging betweensaid members and box for maintaining the latter in a plurality oflaterally shifted positions.

17. The combination with a frame, of wear members mounted therein, adriving box slidably mounted in said members, and means for compensatingforthe wear on the sides of said members.

19. The combination with a frame, of wear members mounted therein, adriving box slidably mounted in said members, and

selectively adjustable means for compensating for the wear on thesidesof said members.

21. The combination with a frame, of

channel. members disposed to embrace said frame, a driving box mountedin said members and independently adjustable plates insertible betweensaid members and box for shifting the latter transversely to said frame.

22. The combination with a frame, of wear members mounted therein, adriving box slidably mounted in said members and independentlyadjustable means insertible between said box and members for shiftingsaid box transversely to said frame.-
